Don't focus on the big truck, if anything, it helps you. Focus on the bikes, because they shoot at you. And for the cars, try to shoot out the windows and driver. Oh by the way, you're not the only one who had trouble with this mission, it took me a few tries too

Does anybody know an easy way to beat "wrong side of the tracks"I keep attemping and i casn freakin do it

I did "wrong side of the tracks", but then died in the course of messing about afterwards and reloaded before remembering I hadn't saved after the mission. It then took me another 6 goes to pass again. I don't really know what I did different the two times I past, but I think it was not getting so close that Smoke can't get his shots on target.

no, you cant use 2 uzis at the same time while riding.yes, you can max out weapon skills while still in los santosand dont shoot tires, on the bikes shoot the passenger and then the driver. in the cars, shoot the passenger and the windshield.

One thing I also found is that if a car starts to flame STOP shooting at it. Remember that gun takes a while to reload so don't keep your finger on the fire button while you aren't targetting an enemy.

This was a biggie for me, I failed it twice before passing it because I just kept my finger on fire and then enemies did more damage to me while I was reloading.

Another thing too is try aiming for the guys sitting on the bikes as they will go down quicker than the bikes. Make sure that you DO NOT target the Big Truck for a while into the mission because you cannot blow him up till the end and you will be wasting your time, not to mention be getting shot up by everyone else while you are trying to take out that Packer.
